  • Patent number: 9366950
    Abstract: A method for simultaneously projecting two images onto a projection surface may include generating a first and second illumination beam based on first and second image data, which are representative of a first and second image, wherein the first illumination beam has electromagnetic radiation having a first property, wherein the second illumination beam has electromagnetic radiation having a second property, which differs from the first property, and deflecting the first and second illumination beams toward the projection surface so that the first illumination and second beam generates a first and second beam spot on the projection surface, respectively, wherein the first and second beam spot is moved over the projection surface so that with the aid of the first and second beam spot, the first and second image are displayed for a first and second observer on the surface, respectively, and the second image is superimposed on the first image.

    Abstract: This invention concerns a method of producing a Pepper's Ghost. The method may comprise projecting an image of a subject onto a reflective and transparent screen (7) to create a virtual image (15) of the subject alongside an object (21). The subject of the virtual image may have a colour temperature and the method may comprise illuminating the object (21) with light having a colour and intensity that results in a colour temperature of the object (21) at least approximately matching the colour temperature of the subject of the virtual image. The method may comprise altering the intensity of light that falls on the object (21) by moving the lighting arrangement towards or away from the object (21) whilst maintaining an intensity of light omitted by the lighting arrangement constant.

  • Publication number: 20110032362
    Abstract: A light guiding device is operable to receive incident light emitted by a light source through a capture surface. The received light exits the light guiding device through an exit surface provided adjacent to and aligned with an aperture of light receiver. In this manner, light from the light source can be inserted into the receiver where it may be combined with additional incident light captured by the receiver. The light source might be a projector and the light projected may correspond to operational data relating to the operation of the receiver or images corresponding to data captured by a further receiver device operating with a different form of sensor or in a different region of the spectrum. In order to improve the composite image observed by a user of the light receiving device, the operation of the light source can be controlled to vary the intensity of the light emitted. In one example, this variation can be in response to the ambient light level, as sensed by a suitable sensor.

  • Publication number: 20100100847
    Abstract: There has been a problem of necessitating a complicated work for establishing a connection capable of intercommunication between a computer as server and a projector as client. When a connection is established between a server 20 and projectors 301 through 30n, a communication command is issued according to UDP-based broadcasting to retrieve connectable projectors 301 through 303. Thereafter, the projector 301 to be connected is selected and is assigned an IP address to establish the connection. In this manner, a user can easily obtain a connection environment capable of intercommunication between the server 20 and the projector 301. A TCP/IP communication command is used to input or output image data, ensuring reliable transmission. Since the authentication can be provided using a keyword projected during the connection establishment, it is possible to prevent an unauthorized access to the projector 301 by an outsider.

    Abstract: A projection system that projects a text or subtitle box onto an image minimizes the contrast between the text box and the image. A transition region surrounding the text box minimizes visual disruption to the image onto which the text box is projected. The positions of optical elements of a text projector enable the text box to gradually fade out. The text projector has a lamp that defines an object plane and a light path modifier. The light path modifier is offset from the object plane, toward the lamp to blend the borders of the text box into the image projected by an image projector.
